blktests: call for agreement to relicense GPL-2.0 files

blktests: call for agreement to relicense GPL-2.0 files

[Shin'ichiro Kawasaki]

Hello blktests contributors,

Recent discussion unveiled a license inconsistency [1]. Currently, each file of
blktests has one of the licenses: GPL-2.0, GPL-2.0+ or GPL-3.0+. Majority of the
blktests code has GPL-3.0+, so the effective main license is GPL-3.0+ (e.g.,
check, common/rc). However, GPL-2.0 and GPL-3.0 are not compatible with each
other [2]. Because the majority of blktests is GPL-3.0+, blktests cannot contain
GPL-2.0 files. All files shall be GPL-2.0+ or GPL-3.0+.

  [1] https://lore.kernel.org/linux-block/20260626045650.GA8752@lst.de/
  [2] https://www.gnu.org/licenses/gpl-faq.html#v2v3Compatibility

As of July 2026, seven files below have GPL-2.0. It is desired to change their
license to GPL-2.0+ (or GPL-3.0+). The list below shows Authors and Contributors
of each file. "Author" means the original file creator who set the license
GPL-2.0. "Contributor" means those who made changes to the files later on.

To the authors and the contributors,

  I would like to call for your responses. Please let us know if you agree to
  modify the license of the files from GPL-2.0 to GPL-2.0+ (or GPL-3.0+).


I will wait for a few weeks to gather responses. Once agreement gets
estabilished, I will ask the authors to submit patches to make the license
change. Any other general comments on this topic will be appreciated also.

And as one of the contributors, here I express my agreement to change the
license of the files :)

I'm fine with making this change.

Thanks,

Bart.

I agree to the license change.
Thank you for your work.

Re: blktests: call for agreement to relicense GPL-2.0 files

[Shin'ichiro Kawasaki]

Three weeks have passed since my call for agreement. Thank you very much to
those who responded. There was no objection to the change. I conclude that
the agreement has been made, and would like to take the next step for the fix.

 - John Pittman did not respond, but I confirmed off-list that he has no
   objection to the change.

 - I did not get a response from Yi Zhang's Red Hat address. I tried to reach Yi
   Zhang via the e-mail address on Yi Zhang's GitHub account, but received no
   response there either. I concluded it is not productive to wait any longer.

   Yi Zhang's contributions to the relevant source files are the two commits
   below:

   A) 38fc272ee91f ("tests/block: add the missing _have_fio check for block/029 block/031")
   B) 06cd1d595571 ("block/031: remove the fio verify.state file")

   These are small changes that added a couple of _have_fio calls and a fio
   option. I think it is reasonable to consider the changes as "de minimis"
   and they do not prevent the relicense.


Bart, Ming and Keith,

  May I ask you to create and post a patch to change the license of the files
  you authored from GPL-2.0 to GPL-3.0+?

  - Bart: block/029,030,031
    Contributors: Christoph Hellwig <hch@lst.de>
		  Li Zhijian <lizhijian@fujitsu.com>
		  Akinobu Mita <akinobu.mita@gmail.com>
		  Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com>
  - Ming: block/040
  - Keith: block/042,043, src/dio-offsets.c
    Contributors: Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com>
		  John Pittman <jpittman@redhat.com>
		  Bart Van Assche <bvanassche@acm.org>

  If you are too busy, please let me know. I can create the patch on your
  behalf, but since this is a license change, it's better if you author it
  yourselves.

Bart and Keith,

  When you post the patch, please CC the contributors, so that they can
  provide their Acked-by tags.

Contributors,

  When you receive the CCed patches, please respond with your Acked-by tag
  to record your agreement to the relicense.

Bart,

  Could you please note in the commit message that Yi Zhang's two commits A)
  and B) above are regarded as "de minimis"? I drafted the description as
  below:

    Because Yi Zhang did not respond to the relicensing request (contacted via
    e-mail addresses on Red Hat and on the GitHub account), and commits A) and
    B) by Yi Zhang are regarded as de minimis, acknowledgement by Yi Zhang is
    not expected.

Thanks in advance for your cooperation.
